- It counts as difficult terrain, excluding impassable terrain.
If unit initiates combat or unit's HP ≥ 25% at start of combat, grants Atk/Spd/Def/Res+9 to unit, unit deals +X damage (if there is a space within 2 spaces of unit that meet any of the above conditions, X = 15; otherwise, X = 7; excluding area-of-effect Specials), reduces damage from foe's attacks by X (excluding area-of-effect Specials), and reduces the percentage of foe's non-Special "reduce damage by X%" skills by 50% during combat (excluding area-of-effect Specials).

Ninja Yunaka Best IVs

Recommended IVs

Stat Superboon/Superbane IV Recommendation
HP (18) HP Superbane ★★★☆☆
Atk (10) No Attack IV ★★★★☆
Spd (10) Spd Boon ★★★★★
Def (9) Def Bane ★★☆☆☆
Res (8) No Res IV ★★☆☆☆

◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws

See the IV Checker for All Units Trait Fruits—How to Change IVs

When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.

+Spd/-Res

The best IVs for Ninja Yunaka are +Spd and -Res. Ninja Yunaka's base 49 Spd is tied for the fastest in the game (as of the time of her release) and should be maximized in order to allow her to quad attack most of her foes.

While both Yunaka's Def and Res are nearly identical, we still recommend -Res as most Far Save tanks in the game deal physical damage and have Distant Counter effects.

How to Use, Explanation

Ninja Yunaka's base kit is also good enough to function as a mobile offensive unit. Emblem Micaiah Ring can give Yunaka an extra action after using an assist to extend her threat range, especially with her warping effect.
